The only unforgivable sin is deliberate cruelty.

The theatre is a place where one has time for the problems of people to whom one would show the door if they came to one's office for a job.

I can't stand a naked light bulb, any more than I can a rude remark or a vulgar action.

Oh you weak, beautiful people who give up with such grace. What you need is someone to take hold of you

It is, perhaps more than anything else, the arrest of time which has taken place in a completed work of art that gives certain plays their feeling of depth and significance.

I can't expose a human weakness on the stage unless I know it through having it myself.

Some things are not forgiveable. Deliberate cruelty is not forgiveable. It is the most unforgiveable thing in my opinion, and the one thing in which I have never, ever been guilty.
